Influence of the Resonant Interaction of Surface Magnetostatic Waves with Exchange Modes on the EMF Generation in YIG/Pt Structures

The characteristics of EMF (U) generation in the thin-film Pt/YIG structures caused by hybridization of propagating magnetostatic surface waves with exchange modes of YIG film were studied. It was shown that at frequencies f* corresponding to the dipole-exchange resonances (DER) the magnitude of EMF...

Zusammenfassung:	The characteristics of EMF (U) generation in the thin-film Pt/YIG structures caused by hybridization of propagating magnetostatic surface waves with exchange modes of YIG film were studied. It was shown that at frequencies f* corresponding to the dipole-exchange resonances (DER) the magnitude of EMF U increases by several times in comparison with the frequencies different from DER (f?f*). The Volt-Watt sensitivity was estimated for the Pt/YIG structures with different geometries of Pt microstrips.
